The ipfwadm-wrapper shell script should be a plug-in replacement of
ipfwadm for backwards compatibility with ipfwadm 2.3a.

The only feature it can't really handle is the `-V' option. When this
is used, a warning is given. If the `-W' option is also used, the
`-V' option is ignored. Otherwise, the script tries to find the
interface name associated with that address, using ifconfig. If
that fails (such as for an interface which is down) then it will exit
with an error message.

This warning can be suppressed by either changing the `-V' to a `-W',
or directing the standard output of the script to /dev/null.

If you should find any mistakes in this script, or any changes between
the real ipfwadm and this script, please report a bug to me: send
an EMail to rusty@linuxcare.com with "BUG-REPORT" in the subject.
Please list your old version of ipfwadm (ipfwadm -h), your
version of ipchains (ipchains --version), the version of the
ipfwadm wrapper script (ipfwadm-wrapper --version). Also send the
output of ipchains-save. Thanks in advance.
